add

var Command = &command.Command{
	Usage: "add --type <file-type> <project-file> <model-file>",
	Short: "add a paleogeographic reconstruction model",
	Long: `
Command add adds the path of a paleogeographic reconstruction model to a
PhyGeo project. The model can be a plate motion model, or a paleolandscape.

The first argument of the command is the name of the project file. If no
project exists, a new project will be created.

The second argument is the valid path of a model file. If there is a model
already defined in the project, its path will be replaced by the path of the
added file. The model can be either a plate motion model (pixels locations in
time), or a landscape pixelation (pixel values on time). Both kind of models
must be compatible, i.e. based on the same underlying pixelation, and have the
same time stages.

The type of the added model must be explicitly defined using the flag --type
with one of the following values:

	geomotion	for a plate motion model
	landscape	for a landscape model
	`,
	SetFlags: setFlags,
	Run:      run,
}
